This version adds the following: - Autodetection and support of the BIOS EDD extensions to work around the 1024 cylinder limit on all but really ancient BIOS's. - To work around some BIOS's which break when EDD is used with older drives, we only attempt to use EDD if the cylinder is > 1023. - Since this new code required more space than we had left, expand boot0 to 2 sectors (1024 bytes) in length. - Add support for boot0 being multiple sectors using predefined constants. If boot0 needs to be extended in the future, all that is required is bumping the NUM_SECTORS constant. - Now that we have more room to work with, add a few more fs type descriptions while making others more verbose.
